Solving the three-dimensional electromagnetic scattering problems by the Padé(1,0) parabolic equation method

采用Padé(1,0)有理多项式,逼近抛物线方程中的拟微分算子,推导出一种易于计算三维电大目标电磁散射问题的Padé(1,0)抛物线方程算法.关于理想导电立方体电磁散射的算例表明,该算法在保证一定精度的前提下,大大提高了计算效率,节约了内存.

With Pade （1,0） rational polynomials used to approximate the pseudo -differential operator of parabolic equation （ PE）, the Pade （ 1,0） PE algorithm was derived. In particular, the algorithm was suitable for computing the scattering from three - dimensional electrically - large objects. The numerical results conducted on the scattering from perfectly conducting cubic demonstrate that the algorithm improved computational efficiency and saved the memory within given accuracy.
